What do you guys think about TTI's on Screamin' Eagle Street Cannons, pros and cons.

 

As long as you install them right you will have nothing but pros. I loved my gutted stock slip-on's with TTI's! They sounded great and the torque increase down low and mid range was awesome. My pipes cracked due to not using the correct size drill bit when installing them so I put them on my brother's bike and replaced my slip-on's with V&H stright shots. I can definitely feel the difference without the TTI's. With a high flow ac and a tuner you will really like the results.

 

Street cannons have catalytic converters in them. You would have to remove every thing in them. That's a lot of money to pay and then de-gut them. Street cannons are not cheap.

 

Yeah decided against them. The guys at Harley didn't think of much of them either.

 

You do not need to remove the cat to install Thunder Torque Inserts™.

We have yet to test an exhaust (other than the super trapp style) that does not experience a significant bump in low and mid range torque from the addition of the TTI's.

It is the single best power improvement, per dollar spent, one can make.
